On the sources of cyclic loads in horizontal-axis wind turbines: The role of blade-section misalignment
(Pergamon-Elsevier Science Ltd, 2018-03)
In this paper we investigate the sources of cyclic loads affecting the structural solicitation and power production in Horizontal Axis Wind Turbines, in particular the role of blade-section misalignment. These loads could ...
Digital image correlation strain measurement of ultra-high-performance concrete-prisms under static and cyclic bending-tensile stress
(Wiley Blackwell Publishing, Inc, 2019-08)
This paper provides experimental results on investigations for the validation of photogrammetric strain measurements of ultra-high-performance concrete (UHPC)-prisms subjected to static and cyclic bending-tensile stress. ...
Meshfree modeling of cyclic behavior of sands within large strain Generalized Plasticity Framework
(Elsevier, 2020-06)
In this publication the u-w finite strain formulation is enhanced with a Generalized Plasticity model for sands. The new model is numerically solved using an Optimal Transportation Meshfree approach that is best suited for ...
Screening for cystic fibrosis via a magnetic and microfluidic immunoassay format with electrochemical detection using a copper nanoparticle-modified gold electrode
(Springer Wien, 2016-10)
This article describes a microfluidic electrochemical immunoassay that features two strategies, viz. (a), the incorporation of magnetic nanoparticles (MNPs) into the central microfluidic channel and acting as a bioaffinity ...
Common root causes of recent failures of flanges in pressure vessels subjected to dynamic loads
(Pergamon-Elsevier Science Ltd, 2008-09-17)
Present rules in fabrication codes are aimed to reduce the probability of fatigue cracks in flanges welded to pressure vessels subjected to cyclic pressure or vibrations. Yet, several leaks and ruptures have recently ...
Electroactive polymers made by loading redox ions inside crosslinked polymeric hydrogels. Effects of hydrophobic interactions and solvent dynamics
(Pergamon-Elsevier Science Ltd, 2016-11)
Electroactive polymers are made by loading redox complexes inside different polymeric crosslinked hydrogels. A redox cation (tris(phenanthroline)iron(II) (TPFeII) is sorbed in anionic, neutral and cationic hydrogels while ...
Constitutive modelling of the mechanical response of a polycaprolactone based polyurethane elastomer: Finite element analysis and experimental validation through a bulge test
(Professional Engineering Publishing Ltd, 2021-05)
The mechanical behaviour of a high performance polycaprolactone based polyurethane elastomer (PCL) up to large strain levels, cyclic loading and equibiaxial stress has been assessed. The PCL can be categorised as a rubber-like ...
Shear behaviour of brick-mortar interface in CFRP retrofitted or repaired masonry
(Pergamon-Elsevier Science Ltd, 2010-04)
There are many unreinforced masonry buildings all over the world. Many of them are located in seismic zones and are, therefore, susceptible to lateral forces caused by earthquakes. The transmission of these forces to the ...
Electrochemistry of Tris(1,10-phenanthroline)iron(II) inside a polymeric hydrogel. Coupled chemical reactions and migration effects
(Springer, 2016-07)
The retention, release, and detection of metallic complexes in polymeric hydrogels are of interest in drug delivery, analytical chemistry, and water remediation. The electrochemistry of the redox complexes inside the ...
Fractographic analysis of austempered ductile iron
(Wiley Blackwell Publishing, Inc, 2016-05-23)
This investigation involves a systematic study of the fracture surfaces of two grades of austempered ductile iron (ADI) broken under quasi-static, dynamic and cyclic loading conditions. The study used electron microscopy, ...
